Correct Answer: D

Rationale: The correct answer is D: avoid caffeine, alcohol, and chocolate. This helps to reduce acid reflux symptoms associated with hiatal hernia. Caffeine, alcohol, and chocolate can relax the lower esophageal sphincter, leading to increased reflux. Elevating legs (choice A) does not address the underlying issue. Drinking more fluids (choice B) can exacerbate symptoms by increasing stomach volume. Increasing roughage (choice C) may worsen symptoms due to increased gastric distension. By avoiding triggers like caffeine, alcohol, and chocolate, the client can effectively manage her symptoms.

Correct Answer: B

Rationale: The correct answer is B: Observe the patient for bleeding. Before a bone marrow biopsy, it is crucial to monitor the patient for bleeding tendencies as the procedure can cause bleeding. This step ensures early detection and prompt intervention if bleeding occurs. Explanation for other choices: A: Explaining the procedure to the family is important for informed consent but not the most crucial before the procedure. C: Administering an analgesic may be necessary for pain management but monitoring for bleeding takes precedence. D: Draping the biopsy site is important for maintaining a sterile field but does not directly impact patient safety like monitoring for bleeding.

Correct Answer: C

Rationale: The correct answer is C: Human, T-cell lymphotrophic virus, as it is the causative agent for HIV/AIDS. This virus specifically targets and infects the body's T-cells, weakening the immune system. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different pathogens that do not cause HIV/AIDS. Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, Treponema pallidum causes syphilis, and Chlamydia trachomatis causes chlamydia. Therefore, the correct answer is C based on the specific viral agent responsible for HIV/AIDS.

Correct Answer: B

Rationale: The correct answer is B because starting birth control pills does not protect against HIV transmission to the baby during pregnancy. The other choices demonstrate understanding of HIV transmission risks and prevention methods. A shows awareness of vertical transmission, C recognizes that not all babies born to HIV-positive mothers are infected, and D acknowledges the potential need for a C-section to reduce transmission risk. Starting birth control pills is unrelated to preventing mother-to-child HIV transmission during pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Clients with metal implants in their body. An MRI uses strong magnetic fields, which can interact with metal implants, causing movement or heating of the metal and potential harm to the client. This could lead to serious injuries or complications during the scan. Overweight clients (choice A), clients over the age of 60 (choice C), and clients with brain tumors (choice D) do not have contraindications for an MRI scan.
